Materials Data on RbHoO2 by Materials Project

RbHoO2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Rb1+ is bonded in a 6-coordinate geometry to six equivalent O2- atoms. All Rb–O bond lengths are 2.94 Å. Ho3+ is bonded to six equivalent O2- atoms to form edge-sharing HoO6 octahedra. All Ho–O bond lengths are 2.32 Å. O2- is bonded to three equivalent Rb1+ and three equivalent Ho3+ atoms to form a mixture of distorted corner and edge-sharing ORb3Ho3 octahedra. The corner-sharing octahedral tilt angles are 0°.

Materials Data on RbHoO3 by Materials Project

RbHoO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Rb is bonded to twelve equivalent O atoms to form RbO12 cuboctahedra that share corners with twelve equivalent RbO12 cuboctahedra, faces with six equivalent RbO12 cuboctahedra, and faces with eight equivalent HoO6 octahedra. All Rb–O bond lengths are 3.18 Å. Ho is bonded to six equivalent O atoms to form HoO6 octahedra that share corners with six equivalent HoO6 octahedra and faces with eight equivalent RbO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Ho–O bond lengths are 2.25 Å. O is bonded in a distorted linear geometry to four equivalent Rb and two equivalent Ho atoms.
